Tile Layout and Pattern Planner

Calculate the number of tiles needed for any room, accounting for pattern type, grout spacing, and waste factor.

Room Length (ft)

Room Width (ft)

Tile Length (inches)

Tile Width (inches)

Grout Joint Width (inches)

Tile Pattern

Straight / Grid (0% extra) Brick / Offset (10% extra) Diagonal / 45° (15% extra) Herringbone (20% extra) Versailles / Mixed (25% extra)

Additional Waste % (cuts, breakage)

Tiles per Box (optional)

Deduction Area (ft², e.g. cabinets, islands)

Price per Box ($, optional)

Calculate Results will appear here.

#### Formulas Used

Net Area: Room Area − Deduction Area

Effective Tile Area (with grout): Atile = (Tile Length + Grout) × (Tile Width + Grout) ÷ 144 [converts in² → ft²]

Base Tiles: Net Area ÷ Atile

Total Waste Factor: 1 + Pattern Waste % + User Waste %

Total Tiles (with waste): ⌈ Base Tiles × Total Waste Factor ⌉

Boxes Required: ⌈ Total Tiles ÷ Tiles per Box ⌉

Estimated Cost: Boxes Required × Price per Box

#### Assumptions & References

Results are always rounded up to the nearest whole tile or box to ensure full coverage.
